Integral equipment bay

Abstract

The invention relates to an integral equipment bay which comprises a framework, a bottom plate, an end plate and an apron board, wherein the bottom plate, the end plate and the apron board are all fixedly arranged on the framework; the framework consists of an upper edge beam, a lower edge beam, multiple cross beams, multiple camber beams arranged between the upper edge beam and the lower edge beam, and end part brackets arranged at two ends; the upper edge beam and the lower edge beam are arranged along the vehicle length direction, and the multiple cross beams are arranged along the vehicle width direction; the upper edge beam, the camber beams, the lower edge beam, the cross beams and the end part brackets are fixedly connected with one another by virtue of fastening pieces; the upper edge beam is fixedly arranged on a vehicle body edge body by virtue of a fastening piece. <0}{0><}0{>According to the integral equipment bay, an overall equipment bay module can be preassembled by virtue of toolings offline; during entrucking, the overall equipment bay module is connected with the vehicle body edge beam, so that the entire car assembling table bit occupation time is shortened, and the entire car assembly efficiency and the equipment bay commercialization degree are greatly improved.

Description

technical field [0001] The invention relates to an equipment cabin of a rail vehicle, in particular to an integral equipment cabin with a high degree of modularization which can be integrally installed on a chassis of a vehicle body, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] At present, there is generally an equipment cabin under the underframe of the EMU, and the equipment under the car is installed in the equipment cabin. It is the installation link of each component in the equipment compartment that can only be entered after the equipment under the vehicle is assembled, and the top of the skirt plate is fixed on the side beam of the vehicle body through the skirt plate lock, and the bottom plate of the equipment compartment is also fixed according to the installation conditions of the equipment under the vehicle On mounts for under-vehicle equipment. This kind of equipment cabin structure not only has low installation...

AI Technical Summary

Problems solved by technology

This kind of equipment cabin structure not only has low installation efficiency, but also due to the manufacturing and installation errors of equipment under the vehicle, the influence of welding deformation of equipment cabin parts, and the structural limitations of the whole vehicle, the main installation dimensions of the equipment cabin have large deviations, and there are excessive local installation stresses and structural problems. Problems such as cracks, uneven flash joints between the skirt plate and the car body, non-uniform radians between the skirt plates, poor overall appearance quality, and poor sealing
